JOHN J'. RICHARDSON, OF CHELSEA, MASSACHUSETTS.

SHOE-MACHINE.

To all whom it may concern Be it known that I, JOHN J. RICHARDSON, acitizen of the United States, residing at Chelsea, in the county ofSuffolk and State of Massachusetts, have invented a new Shoe-Machine, ofwhich the following is a specification.

My invention relates to improvements in machines for cutting and beadingthe soles of shoes, and it consists of the construction, combination andarrangement of parts hereinafter fully described and claimed.

The invention is disclosed in the accompanying drawing, wherein,

Figure 1 is a view in side elevation of a shoe cutting and beadingmachine constructed in accordance with my invention. Fig. 2 is a view inrear elevation of the machine. Fig. 3 is a top plan view of the machine.Fig. 4 is a view in front elevation of the upper portion of the machine.Fig. 5 is a detail plan view of the guide. Fig. 6 is a view illustratingthe cutter and header, the cutter being shown applied to the lower endof the bolt.

Referring to the drawing by reference numerals, 1 designates ahorizontal base which is provided on its upper surface with a vertically disposed socketed member 2. A vertical standard 3 has its lowerend located in the socket of the member 2, said standard being securedin applied position by a set screw 4. Secured to the upper end of thestandard 3 is a horizontally disposed table 5. A pair of bearingbrackets 6 in which is journaled a shaft 7 is secured to the upper sideof the table 5 adjacent the rear end thereof. A pulley 8 is fixed uponthe shaft 7 in alinement with a pulley 9 fixed upon a shaft 10, a belt11 passing about the pulleys. A pulley 12 is fixed upon the shaft and isadapted to receive the belt of a suitable power means. The shaft 10 isjournaled in a bearing 13 secured to the standard 3, and is in alinementwith the shaft 7. The belt 11 passes loosely about the pulleys 8 and 9,and when it is desired to drive the shaft 7, the slack in the belt istaken up by forcing a roller 14 into engagement with one run of thebelt. The roller 14 is journaled in the forked end 15 of a bar 16 whichis slidably mounted on the under side of the table 5 in bearing brackets17. The roller 14 may be forced into engagement with the belt 11 throughthe medium of a foot lever 18 piv- Specification of Letters Patent.

otally secured at one end to the socketed member 2, or it may beoperated by a hand grip 19 formed on the rod. An elbow lever 20 ispivotally secured to the standard 3 and has one of its arms connectedwith the bar 16. Theother arm of the lever 20 is connected to the footlever 18 through the medium of a rod 21 which comprises sectionsadjustably connected by a turn buckle 22. The roller 14 is normallyretained out of engagement with the belt 11 by a contractile spring 23which encircles a rod 24. The rod is secured at one end to one of thebean ing brackets 17 and passes through an eye 25 secured to the bar 16.The spring 23 is secured at one end to that bearing bracket 17 to whichthe rod 24 is secured, and to the eye 25. The roller 14 may be retainedin engagement with the belt 11 by means of a set screw 26 which iscarried by that hearing bracket 17 to which the rod 24 is secured. Thearms of the forked end of the bar 16 are slotted as at 26 to permit theadjustment of the roller 14 on the bar. A plunger 27 is slidably mountedin bearing brackets 28 se cured to the upper surface of the table 5, andit is disposed at right angles with relation to the shaft 7. A- disk 28which is journaled on the inner end of the plunger 27, engages in theperipheral groove 29 of an eccentric 30 fixed on the shaft 7. The disk28 is held in engagement with the periphery of the eccentric 30 by acontractile spring 31, whereby the rotation of the shaft 7 will impart areciprocatory movement to the plunger 27 The contractile spring 31encircles a bar 32 secured at one end to a bracket 33 suitably mountedupon one of the bearing brackets 28. The bar passes through an eye 33secured to the plunger 27. One end of the spring 31 is secured to thebracket 33 and the other end thereof is secured to the eye 33. At itsouter end the plunger 27 is provided with a cutting tool 34 and abeading tool 34 The tools are carried by the lower end of a bolt 35 andsecured thereto through the medium of elements 34 and 34 respectively.The bolt 35 is mounted for a limited vertical movement on hearingbrackets 36 and 37 which are secured to the side of an arm 38, the armbeing secured to and depending from the outer end of the plunger 27. Thebolt 35 has journaled in its lower end a roller 39 which guides thetools over the sole of a shoe held against a rest e0 which is pivotallymounted upon the arm 4L1 of a bracket 42. The

bracket 42 is secured to the underside of the 5 table 5 and projectsforwardly thcreiruu. The arm l1 of the bracket 42 carries set screws 4-3adapted to limit the pivotal movement of the rest 40 in both directions.The lower end of the arm 38 is disposed for movement in the slot le t ota guide bar l5 secured to the upper side of the table and projectingforwardly therefrom.

Assuming that the shaft 10 is in motion, the forcing of the roller l tinto engagement with the belt 11 through the medium 01 the foot lever 18or hand grip 19 will cause the rotation of the shaft 7. The rotation ofthe shaft 7 will, through the medium of the eccentric 30, disk 28 andspring 31, reciprocate the tools. It the shoe is held in invertedposition against the rest. 10, the tool will cut or head the shankthereof, making a dividing line between the shank and the fore part ofthe shoe. The roller 39 engages the shank and causes the tool to make acut or head 0i uniform depth in the shank. The roller 39 is yieldinglyheld in engagement with the shank of the shoe by a spring 4L6. Thebearing brackets 36 and 37 are carried by beaded bolts 47 between theheads of which and the arm 38 are mounted springs 48, said bolts passingthrough the arm 38. If it is desired to make a straight out or head inthe shank of a shoe the brackets 36 and 37 are secured to the arm 38against movement thereon by screws 49. When it is desired to make acurved cut or bead in the shank of a shoe the screws l9 are removed anda curved guide 50 is secured to one side of the guide bar to forengagement by the bolt 35, the bolt during its movement traveling overthe curved edge of the guide. The springs L8 hold the bolt 35 inengagement with the curved face of the guide. As the spring 23yielding'ly retains the roller 14 out of engagement with the bolt 11,the machine will be thrown out of operation as soon as the pressure isremoved from the foot lever 18 or the hand grip 19. If it is desired tomaintain the machine in constant operation the bolt 26 is turned intoengagement with the bar 16.

When it is desired to out and bead the sole of a shoe, the shoe isplaced against the rest 40 with the sole uppermost, after which themachine is set in operation. The operation oi the machine carries thecutting and heading tools 34- and 3%, respectively, across the shoesole, cutting and beading the same. As the cutting and beading tools 3dand 34%, respectively, are mounted upon the plunger 27 for verticalmovement relative thereto, the tools may follow the curvature of theshoe sole, and as the tools are mounted upon the plunger for horizontalmovement relative thereto, the cut and bead may be formed vuring thetools 341: and 34 against horizontal movement with relation to theplunger 27, the tools being adapted to be secured against such movementthrough the medium of the screws 4-.9. lVhen the cut and bead is to bemade on a straight line the guide 50 is removed from the machine.

From the foregoing description, taken in connection with theaccompanying drawing, it should be apparent that I provide a machine inthe use of which a shoe shank may be readily and quickly cut and beaded,that the machine is comparatively simple and durable of construction,and that it may be manufactured and sold at a comparatively low cost.
